Major disappointment I’m afraid. Wife bought me Class 37 Concrete Bob weathered for Christmas and to cut a long story short I’m now on my third loco. Put it on the track to find the same issues - lights not working again, flickering and at one end no cab light at all. So frustrated that they did not check this before it left the premises. Given that I’ve already wasted so much time phoning and going to the post offfice I tried opening it up to have a look myself (I know, I know). The lights seem to rely on little prongs to make connection from the led circuit to the chassis for power. They are plainly not connecting properly. So I tweeked the prongs and managed to get the front and rear working (still no cab light at one end) although there was still some flickers on the rear lights ( on the front end) as the loco went forward - but it was better than before. I thought stuff it I’ll live with that and so went to put a decoder in - fan bl%&#£y tastic now a screw has lost its head some how and I can’t get the body off. I’m as well chucking the heap of junk in the bin. Sorry for the rant but at £150 this shouldn’t be happening.
